Hi Pavel,
I am developing a profiling tool depending on record & replay feature of
QEMU for RISC-V.
Here I'd like to ask you some questions.
First, is it possible to record & replay a Linux system by this feature
in theory? I mean keep the strict instruction
sequence of each process and kernel, for a very simple image, with only
timer and UART.
Second, is it planed to support RISC-V?
Thanks very much.
Best regards,
Zhiwei
